The trailhead for Osprey Falls is about three miles down the narrow, dirt Bunsen Peak Road. The turn off for this road is just above Rustic Falls and five miles south of Mammoth. The small parking area is on the right side of the road and is not well-defined, but should be marked. This area was burned extensively during the 1988 fires, and most of the Douglas firs-normally resistant to ground fires-burned. This indicates it was a hot, fast-moving fire. It will take several human lifetimes for this area to return to a mature Douglas fir forest.
